Redukcija mikroflore u mariniranim filetima pilećih grudi pakovanih u vakuum

Abstract

The aim of this study was to determine the effect of different marinade solution on the microbiome of chicken breast fillets packaged under vacuum and stored at 4°C. Three types of marinade were tested. A total of 120 chicken breast fillets were marinated in control (6% NaCl) or three different marinades: 6% NaCl and 2% sodium tripolyphosphate; 6% NaCl and 2% sodium citrate, and; 6% NaCl, 1% sodium tripolyphosphate and 1% sodium citrate. Microorganisms were enumerated on the first day of testing (day 0) and on days 7, 14, 21 and 28 of chilled storage. Marination resulted in significant differences (p<0.05) in the numbers of total viable counts, Enterobacteriaceae, lactic acid bacteria and anaerobic bacteria counts. The combination of 6% NaCl and 2% sodium citrate is the most appropriate marinade option for reducing the growth of the examined bacterial groups in vacuum-packaged marinated chicken breast fillets during chilled storage.

Cilj ovog rada bio je da se utvrdi uticaj različitog načina mariniranja na mikrobiotu fileta grudi brojlera pakovanih u vakuum i čuvanih pri 4°C. Ispitivane su tri vrste marinade. Ukupno 120 uzoraka (korišćenih za dva ponavljanja) marinirano je u kontrolnom (6% NaCl) i tri različita tretmana: 6% NaCl i 2% natrijum tripolifosfat (E1), 6% NaCl i 2% natrijum citrat (E2) i rastvor sa 6% NaCl, 1% natrijum tripolifosfata i 1% natrijum citrata (E3). Brojanje mikroorganizama vršeno je prvog dana (0 dan), 7., 14., 21. i 28. dana skladištenja. Utvrđene su statistički značajne razlike (P<0,05) između mariniranih uzoraka u ukupnom broju mezofilnih bakterija, Enterobacteriaceae, bakterijama mlečne kiseline i anaerobnim bakterijama. Utvrđeno je da je kombinacija 6% NaCl i 2% natrijum citrata najprikladnija za redukciju rasta ispitivanih grupa bakterija u mariniranim filetima grudi brojlera pakovanih u vakuum i skladištenih pri 4°C.
